A Tasmanian man has gone missing after leaving a campsite to go kayaking late in the night, a move his friends have described as "out of character".
Search and rescue efforts have been going since late Friday night two hours after Andrew Donohue left to go fishing off the state's northwest coast at Perkins Island at 8.30pm.
His empty black and blue kayak was found on Saturday morning by searchers, which have included marine police, the Westpac Rescue Helicopter, local police, fixed-wing aircraft, ground search and rescue crews, and civilians.
